What does bar mean in a car?
1 Answers
Bar in a car refers to the unit of tire pressure. Tires are an essential component of a vehicle, being the only part that comes into contact with the ground, and they directly affect the driving stability and safety of the car. Tires are made of rubber, and rubber products can deteriorate over time, so tires need to be replaced periodically. Tire pressure is crucial for tires—it should neither be too high nor too low. If the pressure is too low, the tire may develop wave-like deformations during high-speed driving, increasing the risk of a blowout and reducing the tire's lifespan. Conversely, if the pressure is too high, the contact area between the tire and the ground decreases, negatively impacting the car's handling and driving stability.
